ADJUSTABLE SUPPORT FOR WIND-SHIELDS.

No. s49,733.

justably securing two members together, and. I0 a practical applicationof my support-is best illustrated as shown applied to a wind-shield forautomobiles. It Is obvious, however, that itis not limited to suchapplication alone, but may be employed wherever it is r desired to use afolding or adjustable support.

. Among its many advantages is its capability of being adjusted andlocked by a single member and the small s ace-required .to operate thesame in, other a vanta es be- 20., ing 1n the permanency of the grip, wich is most essential when applied to the windshield of a vehicle thatis subject to constant I or severe jolts and pressure from the air.

In the drawings, Figure 1 is a perspective e elevation of my device aplied to a windshield with'the wind-shiel unfolded. Fig. 2 is aperspective elevation of my device as the same appears with thewind-shield folded. Fig. 3 1s a detail side elevation with parts 30broken away. Fig. 4 is a detail front elevation with-parts broken away.Fig. 5 is alongie tndinal section of the clam ing parts. Fig.6 is across-section on the inc 6 6 of Fig. 4. Fig. 7- is a plan view of theclamping-ring,

, 3 5 and Fig, 8 is a plan view of the uide-sleeve.

Referring now more particuIarly to the drawin s, 9 represents asupporting-bracket,

- hereins own of triangular form andadapted -to be secured to a suitablesupport 10 by. the

0 .means as shown at 11, the support in this instance being the-lowerframe of a foldable Wind-shield that is provided with a glass window 13,said support bein secured to. the dashboard 14 ofa vehicle, W ich isrepresent- 5 ed as a whole at 15. As a further means for securing' thebracket and maintaining it in its proper'position I provide a brace 16,that is connectedto the bracket in any suitable man' ner, or, as shown,by providing a stud 17 on the bracket, that is adapted to cooperate witha female joint in the brace, said brace having a connection with anysuitable support, it being herein shown as attached to t Specificationof Letters Patent.

Application filed August 18,1906. Serial-No, 331,218.

' receive the threa e frame of Patented April 9, 1907.-

the vehiclea't 18. Secured to the frame 10 by means of a'hinge is theadjustable. frame 19, that is also-provided withawindow 20. The bracket9 is (provided with an eye 21 to integrally with the which the brace 24is slidably mounted.

ed shank 22', that is formed Y 'de-sleeve' 23, said I guide-sleeve beingof tu ular form and within- The sleeve is cut away on its side adjacentl' to the shank, asshown at 25, so as to permit the clamping-ring 26 tocome in contact with the brace 24, said clamping-ring having a concaveface, as shown at 27 so as'to permit it to engage the brace,'theindentations 28' on the edge of the clamping-ring confo to the exteriorsurface of the brace inorder t at a larger frictional .clampi -surfacemay be presented to the brace. e clamping-ring 24 is interposed betweenthe eye on the bracket and the guide-sleeve with its concaved surfacetoward the sleeve, it being suitably apertured, as shown at 29, to slideon the threaded shank 22, and to prevent its rotation thereon I rovide astud, 30 to fit within thelongitu 'nal oove 31 inthe shank. On theopposite slde-of the eye from which the guide and clampin -ring areplaced I rovidea clamp3'2, threa ed to cooperate w th the threadedshank, and between said eye and clamp is a washer 33, also havin a stud34, similar to the stud 30 and operating in the same manner ,to preventthe-rotation of the washer on the shank. The brace 24 is pivotallyattached at one end, by meansof the eye 35 and pin 36, to the adjustableframe 19 at a point thereon so as to bring its screw.

capped end 37 abuttin "against the guidesleeve, or the end of the %r acemay be headed, so as to limit its movement within the guide.

The device, .as'just described, with the; brace 24 secured to the.adjustableframe and the headed end abutting against the guidesleeve, isshown in 'Fig. 1, and to secure the two portions of theframe when in theosition shownthe clamp is.turned on the s ank of the guide-sleeve so asto draw the brace 24 and guide-sleeve hard against the clamping- TCOring, which in turn is pressed against the surface about the eye, wereupon the frictional engagement between the parts prevents rotation ofthe guide-sleeve or a sliding movement ofthe brace 24 relative thereto.

When it is desired to fold the windshield,

but it is obvious that where less strength isrequired only one of mydevices in ay be used, nor are the braces IG'essential, except forstrength.

It is obvious from the foregoing description that I do not limit myselfto the precise details of constructioinas there are manymodifications oithe parts that might be made Without departing from the spirit ofmy'inof said shank on and means for preventing movement of any of saidparts relative to each other.

Having now described my invention, What I claim is- The combination witha wind-shield. hav- "ing a fixed portion and a foldable' portion hingedthereto, of an adjustable support for said hinged portion comprising abracket se cured to the fixed portion, a guide-sleeve provided with athreaded shank rotatably mounted in said bracket, a clamping-ring onsaid shank interposed between said guide sleeve and said bracket, abrace pivoted to said hinged portion and slidably'engaging said sleeve,and a clamp engaging the threads the opposite side ol said bracket fromsaid clainp1ngr1ng, whereby a I looking or releasing of the sleeve andbraces is vention, the gist of which is the provision of av Isupporting-bracket, a guide-sleeve capable of a partial rotation'mountedon said bracket, a brace slidably mounted'in said guide-sleeve,

effected by the movement substantially as described.
